Version 0.9 Beta 1 Released

This is an important release as it adds if-then-else constructs, and code blocks, as well as internal variables.

Add blocks of expressions separated by semicolons. For example the following expression is parsed correctly: "c=a+cos(b); return c"

Add local variables in blocks. For example the following expression is parsed correctly: "int c=a+cos(b); return c", and in this case the expression export only 2 global variables, a and b (c is local)

Add if-then-else expressions

Skip EOL tokens in the expression parsing
