license) and rebased the ExpressionParser from double on the MAPM data type.
Currently, the binary operators are not supported anymore, but the imprecise
calculations were getting on my nerves. I think a lot more neat functions
could now be supported, but I have not looked into it further. I also didn't
dare look closer at the C code of the library, but it seems to be well
tested. It's portable by all means, I guess even if the target platform has
8.3 char file names to hold the code... Luckily, the library inclused a C++
wrapper class for the data type (MAPM) which makes it fairly comfortable to
use and hides the ugly C stuff and messy memory management.
The result seems to be quite nice so far. Previously, I couldn't even calculate
my finances without eventually getting some rounding errors.

* it supports , and . for the decimal point
* it gives parse errors and where the error occured
* it supports more functions
