* merge trunk into JS_BDDCML (WIP)
* merge trunk and JS_bddcml, successfull build
   error in load_mesh passing
made BDDCML work under 1.7
updated to changes in BDDCML interface
meshdim set properly
properties of the problem printed
few changes for passing conductivity on elements to BDDC solver
better generation of weights for BDDCML solver
* mergeed changes from branches/JS_1.7_bddcml
* does not compile, need further work
* minor fix in FindBDDCML.cmake
Fixed bug in Field::set_time.

... in  field_base_impl.hh 

* msh_gmshreader  : typo
* type_output : enhanced documentation
* extended test18 to cover fixed error
this commit is just for backing up sorption.cc file
Fixed test 16.

* modify reference data for fixed set_time method in Field
* transport.cc: update time dependent BC  only when changed
* basic documentation to flow/old_bcd.*
* removed warnings for implicit conversions during reading input
* more specific warining for lonely elements in mesh
optimization of all code (first part)
optimization of all code (second part)
optimization of all code (last part)
optimization of all code - correction
* added new fparser ver. 4.5.1 (should have better support of new compilers
* fixed some warning in type_record
* added description getters into type_output, removed description getters from Record, Selection
* merged changes in transport (removed unnecessary code)
sorption affects concentration of  dissolved chemicals, but results have to be verified, this commit is just for backup
optimization of all code (remove warnings)
