[mariomorvan]

• [x] implement analytical 1D model as in Cracchiolo et al II
• [x] Performance tests
• [x] Speed tests
• [x] warning for possibly overlapping spots

Update the rest of the code

• [x] udpdat other class named as 2D
• [x] connect 1D and 2D Star classes with inheritance?

last two tasks to be kept for further (optional) improvements:

• [ ] or have a general class which could be 1D or 2D depending on the use...!! parameters given or method used
• [ ] could even use 1D computation for simple 2D cases --> smart!!
