Update to patched version of cppad-20140612
Squashed commit of branch 'atomic_test'

    New 'R-functions'
    -----------------
    - pgamma, qgamma, pnorm, qnorm
    - Argument 'give_log' is deprecated for all 'p' and 'q' functions.

    New macro TMB_ATOMIC_VECTOR_FUNCTION
    ------------------------------------
    - Atomic incomplete gamma function
    - Atomic inverse incomplete gamma
    - Atomic matrix inverse
    - Atomic matrix multiply
    - Atomic lgamma
    - Atomic logdet

    Other:
    ------
    - Eliminated compiler warnings
    - OS X precompile instructions
    - New example to demonstrate qgamma (transform.cpp)
Update to Eigen 3.2.2
Fixed a few more warnings:
    Warning: comparison of int and size_t in REGISTER_ATOMIC macro
    un-initialized variable warning for parallel case
    Eliminate un-used variable warning in myReverseSweep
    Eigen: Eliminate un-used typedef warning

Merge pull request #52 from kaskr/testing

TMB version 1.1
Remove garbage folder
expm: use the same number of iterations for derivatives as function value
(Note, one minor detail is still missing: The norm of A^T is not the same as norm of A...)
density namespace: Add missing N01 vector method
Numerical robust integration of incomplete gamma function.
- Should eliminate warning 'integrate incomplete gamma function unreliable'
Gamma integration transformed to log.
Makefile: Allow partial report (not require run all examples)
Makefile: static pattern rule to easily run single examples
incpl_gamma: avoid numerical integration in special case n=0
