Erlang prototyping for Rammbock.

To compile tools:
1. Launch erlang shell
> erl
2. compile
c("percompile").
c("readfile").

To compile S1AP files:
1. Load compiler
l(percompile).
2. Compile asn.1 specification set
percompile:compile("s1apasn/S1AP.set.asn").

To decode a binary message:
1. load the compiled S1AP module
l('S1AP).
2. load the readfile module
l('readfile').
3. read the binary message
Bin = readfile:readfile("binaries/initiatingMessage.s1").
4. decode
'S1AP':decode('S1AP-PDU', Bin).
