Crash when calculating normalisation for model with two nearby resonances

Description (last modified by Thomas Latham)

Bug in LauIsobarDynamics::calcDPNormalisation(), around line 829 in ​https://laura.hepforge.org/doc/doxygen/v2r1/LauIsobarDynamics_8cc_source.html#l00829 When you have two resonances, one close to threshold, you assume that res1Max is smaller than res2Min, while if the two resonances are close together, this may not be true. I had this problem running with Lc(2880) and Lc(2940) in Dp spectrum. I had to add another "if" which checks that if res1Max>res2Min, one just needs to divide the DP into two regions, (m13min, res2Max) and (res2Max, m13max). I suspect similar thing can affect other cases.

(In [119]) Tidy up code for determining the integration scheme once and using for all reclaculations thereafter, addresses #11. Also fix (in this v3 branch) the bug in the determination of the scheme, addresses #35.

(In [120]) Fix bug in determination of integration scheme with close together narrow resonances, oktotest #35

(In [122]) Merge the bug fix into the v2r1p1 branch, addresses #35
