Possible fix: compilation error: close,lseek not declared
Remove unnecessary test case.

This test case can be derived from those already tested:
- mul(a, 1) == a
- mul(a, inv(a)) == 1
Annotate mul 2,3 test cases
doxygen: Don't make latex and man docs.
Fix compilation error
Implement fq tests.
Report number of failed test cases

TestCase::execute returns the number of failed test cases.
If this is not 0, rnc-test-fq exits with non-zero exit status.
Provide function to generate random elements of fq_t
Implement matrix test case: Bootstrap (I==I)
Compile with strict warning policy (-Wall -pedantic)
Purge compiler warnings
Add level of abstraction: fq_t* <- Matrix
Implement custom Mersenne Twister PRNG
Add function to mt.h to generate elements of the finite field
Add output to rnc-test-rnd
Install test binaries too (so they can be debugged)
Change the representation of matrices

The code is only partially changed; it will not compile
Deny copying Matrix objects (Known bug: no deep copy ==> double free())
Add function: copy to contiguous memory area
Fix saving matrices into files
