Refactor launch package

Before adding some functionality to aoi (objectionary/aoi#39, objectionary/aoi#40, objectionary/aoi#41) most of the code needs to be refactored here. First of all launch package need to be refactored.

Here:

ddr/src/main/kotlin/org/objectionary/ddr/launch/Combiner.kt

Lines 43 to 45 in 7a013e8

	private val logger = LoggerFactory.getLogger("org.objectionary.ddr.launch.Combiner")
	private val sep = File.separatorChar
	val documents: MutableMap<Document, String> = mutableMapOf()

global variables are defined. documents variable is modified in functions launch and buildGraph. Then documents is used throughout the program, and also in aoi.

The functions themselves here also do too much, so decomposition is broken. I think this code should be made more object-oriented. @yegor256, @mximp, WDYT?

Replace Document type (MutableMap<Document, String> -> MutableList<Document>)

ddr/src/main/kotlin/org/objectionary/ddr/sources/Sources.kt

Line 48 in d9d6fcf

val documents: MutableMap<Document, String> = mutableMapOf()

documents variable is used throughout the program, but it has never been used as a Map. Now it is handled like List of documents using only keys without values. Also there is probably no scenario where we might need to use it as a Map. So its type must be changed to MutableList

Release version 0.0.10

The launch package was completely refactored. Now this changes are necessary to refactor aoi and aoi2.

@yegor256, could you release this changes, please?

Fix `pos` attribute generation

In this example (taken from src/test/resources/integration/in/basic_cycle/basic_cycle.xmir):

[] > classA
  classB > @
  [] > doA
    stdout > @
      "A"

[] > classB
  classA > @
  [] > doBA
    ^.doA > @

XMIR listing of object classB looks like this:

<o abstract="" line="9" name="classB" pos="0">
   <o base="classA" line="10" name="@" pos="2"/>
   <o abstract="" line="11" name="doBA" pos="2">
      <o base="^" line="12" pos="4"/>
      <o base=".doA" line="12" method="" name="@" pos="5"/>
   </o>
</o>

DDR gives result transformed XMIR with such classB object (taken from src/test/resources/integration/out/basic_cycle/basic_cycle.xmir):

<o abstract="" line="9" name="classB" pos="0">
   <o base="classA" line="10" name="@" pos="2" ref="3"/>
   <o abstract="" line="11" name="doBA" pos="2">
      <o base="^" line="12" pos="4"/>
      <o base=".@" line="12" method="" pos="9"/>
      <o base=".doA" line="12" method="" name="@" pos="5"/>
   </o>
</o>

As an EO code, classB object should look like this:

[] > classB
  classA > @
  [] > doBA
    ^[email protected] > @

So pos of .@ equals "5" and pos of .doA equals "7". But this is not the case in the XMIR file.
We either need to delete thepos attribute for objects that are related to DDR working process, or handle their pos attribute correctly.

Bug when generating ${PATH}_ddr directory

jacoco won't be able to collect coverage data

thanks to this line: https://github.com/objectionary/ddr/blob/master/pom.xml#L134

see how we deal with it: https://github.com/yegor256/takes/blob/master/pom.xml#L372

let's use jcabi-parent

See how it's done here: https://github.com/objectionary/eo-files/blob/master/pom.xml#L27-L31 This will help automate deployment to Maven Central

Java heap space error

Right now if you look at the pom.xml file you'll see commented out code for .jar creation.
If you uncomment it - you'll see that build fails with "Java heap space" error.
I tried setting heap space like this, didn't help

<configuration>
  <argLine>-Xmx1024m</argLine>
</configuration>

We need to be able to create jar with dependencies to launch the app from console.

Implement Workflow interface

For more general use of the DdrWorkflow class in other projects (objectionary/aoi#63), it must be reimplemented.

Other projects use similar logic, so we need to associate the DdrWorkflow class with others. Otherwise, it turns out a copy paste (AoiWorkflow class)
