First version of parameter file parser. Should be able to:
- Read integers
- Read floats
- Read doubles
- Read strings
- Ignore comments that start with '#'
- Validate that integers are not written as floats in the input file
- Check whether two values are present on the same line
- Print the contents of the structure that holds all parameters read from the file
I had to add ../src/parser.c to the Makefile.am in the tests directory to get make check working. Not sure if this is the correct way of doing it.
