This is an update to the cosmic track splitting validation. It adds more variables into the tree, including the errors for split and original track variables.

I was asked by the conveners to create this pull request for the cosmic track splitting validation.

This is a backport of pull request #2452 in 71X.

This pull request is fully signed and it will be integrated in one of the next CMSSW_7_0_X IBs unless changes (tests are also fine). @nclopezo, @ktf can you please take care of it?

@davidlange6 do we need this in 70X at this point? If not any objections to closing it?

[frmeier]

Sorry for the late reply, was away and traveled.
Although it does not hurt if we get it later in, it doesn't harm to put
it in now. Changes are pretty orthogonal and having it in 70 is handy.
Same justification applies to #2630 and #2331 (where the latter may be
rated more important).

[ktf]

Do we actually need this in 70X?

[mmusich]

Since we are going to get TkAl AlcaRecos processed in 70X for the CSA14 exercise I would say yes

[frmeier]

Whenever we have samples in 70X we need it.

[frmeier]

This has been discussed at yesterday's AlCaDB meeting. Yes, it is needed to validate the dataset we will soon receive. Please proceed.

Hi!
As @frmeier pointed out, this PR is needed for the cosmic samples requested within CSA14.
