VB: Added option to read in controlling parameters for the test*.f90 programs
at runtime. If no input file is supplied when running any of the test* programs, the programs run with compiled-in default values as before. Optionally, a file 'test_parameters.in' can be supplied. In that case, each test* program checks for valid replacement parameters in the following format na 7000 nev 3000 nblk 32 where: - the order of lines does not matter - any, all or none of the specified lines need be present - na is the marix dimension for which the test is run - nev is the number of desired eigenvalue/eigenvector pairs - nblk is the algorithmic block size, usually a relatively small number 16, 32, 64 . Unreasonable values should be avoied, please check first.
