A brief scanning through the paper "Numerical Transform Inversion Using
Gaussian Quadrature" from den Iseger does indicate the complexity of the
algorithm. But GSoC project or not, can't we work on it, step by step? As I
would love to see a contender for Matlab's ilaplace on open source front!!

Thanks a lot for the roadmap. Of the options provided, I found the
'Cython'ization of Cluster great. Would it be possible to do it as the
Summer project if I spend the month learning Cython?
