operator() of the PairWiseCoulombCollisionFunc class. Performs Coulomb collisions at the cell level by calling ElasticCollisionPerez.

Parameters

[in]	I1s,I2s	is the start index for I1,I2 (inclusive).
[in]	I1e,I2e	is the stop index for I1,I2 (exclusive).
[in]	I1	and I2 are the index arrays. They determine all elements that will be used.
[in,out]	u1	and u2 are the velocity arrays (u=v*gamma), they could be either different or the same, their lengths are not needed,
[in]	w1	and w2 are arrays of weights.
[in]	q1	and q2 are charges. m1 and m2 are masses.
[in]	dt	is the time step length between two collision calls.
[in]	dV	is the volume of the corresponding cell.
[in]	engine	the random engine.
