added a simpler constructor, assuming modifiers will do for more complex cases; added ref to the extended particle ... based on comments from Anders, will need to implement more constructors instead of the modifiers

L1MuonParticleExtended to add more handles to details of standalone L1 muon inputs
produce a collection of L1MuonParticleExtended. Details are available only for CSC. For other detectors, it's only marginally more useful than L1MuonParticle. Needs work from other areas
missing dependencies
produce L1TkMuons from L1MuonParticleExtended as input. Full functionality of L1MuonParticleExtended is still not used (current impl would've worked with just the L1MuonParticle with a few extra hacks)
empty already
fix typo filling sigmaEta and sigmaPhi
