Scala REPL with UACalc objects

1. Download Scala from this page.
2. Install Scala.
   Follow the instructions given on the download page. For Ubuntu users, you will download a file called something like scala-2.10.3.tgz. Unpack this file and put a link to the scala/bin directory in your path. For example, do something like the following:

   cd ~/opt/scala  # where you downloaded scala-2.10.3
   tar xvzf scala-2.10.3.tgz
   echo "export PATH=$HOME/opt/scala/scala-2.10.3/bin:$PATH" >> ~/.bash_profile
   source ~/.bash_profile
   

3. Download uacalc.jar.
   Either point your browser to http://uacalc.org/uacalc.jar OR do

   wget http://uacalc.org/uacalc.jar
   

4. Start the Scala REPL with UACalc dependencies.
   In the directory where uacalc.jar is located do `scala -classpath uacalc.jar`.

   williamdemeo@kap:~/UACalc/UACalc_CLI/Jars$ scala -classpath uacalc.jar

5. Import UACalc classes and make some objects.

   scala> import org.uacalc.alg.conlat.BasicPartition
   import org.uacalc.alg.conlat.BasicPartition
   
   scala> val a = new BasicPartition("|0,1|2,3|")
   a: org.uacalc.alg.conlat.BasicPartition = |0,1|2,3|
   
   scala> a
   res2: org.uacalc.alg.conlat.BasicPartition = |0,1|2,3|
   
   scala> val b = new BasicPartition("|0|1,2|3|")
   b: org.uacalc.alg.conlat.BasicPartition = |0|1,2|3|
   
   scala> a.compose(b)
   blocks: [[0,1],[2,3]]
   res3: org.uacalc.alg.conlat.BinaryRelation = [[0, 0], [0, 1], [0, 2], [1, 0], [1, 1], [1, 2], [2, 1], [2, 2], [2, 3], [3, 1], [3, 2], [3, 3]]
