1.2.0 FINAL BETA

Some errors in the parser fixed, the erf and erfc functions have been
updated, more exceptions have been added. The load function can now load
images and has been improved. More bernoulli constants have been added
and a lot of numerical features have been ported. The physics library
has been extended. FFT has been completely renewed, the muted system has
been improved (for most cases nothing changes). Added increment and
decrement operators (only as suffix) and a heatmap plot. Extended the
matrix and prepared some BLAS L1 / L2 (will be integrated in one of the
next major releases).
