Function for generating initial and endpoint-conditioned Markov process sampling paths for a given discrete-time transition matrix

1	rNijTRiT_Unif(tmabs, te, gm, tpm)

`tmabs`	matrix of absolute transition frequencies
`te`	time elapsed in transition process
`gm`	generator matrix
`tpm`	discrete-time transition probability matrix, matrix exponential of gm

Function for the simulation of paths from an endpoint-conditioned Markov process. Returns number of transitions NijT and cumulative holding times RiT.
