Erste Version für asymptotische Formel
für Ei in cython.
Implemented a first version of Ei
using asymptotic formula when possible and
increasing precision when neccesarry.

I copied a crude estimate from the mpmath sourcecode.
Don't know where it comes from but it seems to work in practice.

Merge remote branch 'origin/incgamma-new' into incgamma-new

Conflicts:
	psage/modform/maass/inc_gamma.pyx
Now incgamma_int uses the new Ei function for n=0.
The speed is better than mpmath but it doesn't feel like formula 1.
Fixed division by zero by replacing the double eps
with a RealNumber eps.
Working on the symmetrization of the linear system. Everything compiles...
Working on symmetrization still. There are still
changed stuff (have to commit so I can pull)
Merge branch 'symmetrize' of github.com:fredstro/psage into symmetrize
C-Interface updated: intgamma_nint_c
uses the new implementation for n=0.
Fixed the symmetrized version of setting up the system. This is contained in the function setup_matrix_for_harmonic_Maass_waveforms_sym
and is used by default if the number of cusps is 1 or 2.
To test using the old algorithm, pass the parameter use_sym=0 to _get_element()
Working versionof incgamma with C interface and a substantial speedup.
Merge branch 'master' into incgamma-c
Merge remote branch 'origin/symmetrize' into sym-and-incgamma_nint
Merge branch 'incgamma-new' into sym-and-incgamma_nint
Merge branch 'master' into sym-and-incgamma_nint
Removed a emacs file
and made setup_harmonic... say what it is (if it's sym it should say so instead of sv).
Merge branch 'master' into incgamma-new
I fixed my symmetrized algorithm.
fixed precision issues.
