Added all methods of linear system of 2 eq of 2nd order
Added all methods of linear system of 2 eq of 2nd order
Merge branch 'sysode_linear_2order_2eq' of github.com:KDMOE/sympy into sysode_linear_2order_2eq
Removed .bashrc file
Issue #7537: Add alias for some of the methods in sympy.sets

This commit adds aliases for some of the existing methods so as to be
compatible with Python's builtin set/frozenset type.
Split the module sympy.physics.quantum.fieldoperator

into boson, fermion, and operatorordering.
code style fixes
Added new methods along the Ray class
Merge pull request #7556 from flacjacket/rewrite_fix

Fix `Basic.rewrite()` behavior
Add wavenumber property
Added egyptian_fraction function for Egyptian Fractions calculation
Merge pull request #7557 from skirpichev/4122_egyptian_fraction

Added egyptian_fraction function for calcualting Egyptian Fractions
do not import boson, fermion and operatorordering by default
Renamed BosonOperator and FermionOperator

Renamed BosonOperator and FermionOperator BosonOp and FermionOp, to be consistent with how other model specific operators are named in sympy.physics.quantum (e.g. the operators in the spin module).
Updated docstring tests to new module imports
Merge pull request #7553 from amitsaha/sets_compat

Issue #7537: CPython set/frozenset compatible FiniteSet interface
restored (anti)commutation relations for independent bosonic (which was lost in the restructuring of the modules)
Corrected func_coef
Add equation rewrite methods
Added code minus tests
