Reduce fit errors in HCal local reco to a summary

[mark-grimes]

Running HCal local reconstruction results in thousands of fit errors at 140 pileup. Whilst the cause of this is investigated, this pull request suppresses each individual message and instead outputs a message once per event detailing how many times each error occurred.

So instead of ~16k occurrences of e.g.

%MSG-w HybridMinimizer:  HcalSimpleReconstructor:hbheUpgradeReco  16-Jan-2015 03:08:37 CET Run: 1 Event: 2002
HybridMinimizer::Minimize : Minimization did NOT converge, Edm is above max
%MSG

There is now one occurrence of

%MSG-w HcalSimpleReconstructor:  HcalSimpleReconstructor:hbheUpgradeReco  16-Jan-2015 03:08:37 CET Run: 1 Event: 2002
Fit errors produced:
    17501 successful fits.
    Error 1 occurred 176 times.
    Error 2 occurred 2446 times.
    Error 3 occurred 16455 times.
    Error 4 occurred 1701 times.
