Modify README so that user can build 64 bit windows binary
Fix a bug in Makefile.win: __WIN32__ should be _WIN32
matlab Makefile modified, octave removed
Modify SHVER from 1 to 2.
Change the year of COPYRIGHT from 2013 to 2014
modify matlab/train.c to check if the label vector is in dense format.
fix the following bug

-	model_->bias = (int)ptr[0];
+	model_->bias = ptr[0];
Merge branch 'master' of svm.csie.ntu.edu.tw:liblr
initialize Gnorm1_init with NAN
initialize Gnorm1_init with -1
stopping condition of l1 solvers uses 1-norm rather than inf norm
(wrong description in README)
Merge branch 'master' of svm.csie.ntu.edu.tw:liblr
Expand the expression of blas to fix the compiling error
use __all__ in Python interfaces to make sure only useful things are visible to the users
add two functions get_decfun_coef and get_decfun_bias
replace long int with size_t in linear.cpp and train.c
1. use "extern C" in blas to make sure the compiled function names are always not mangled.
2. replace ``#'' with ``='' in matlab/Makefile
remove ^M in the end of each line in make.m
To support nnz > 2^32, change the data type of the variables related to nnz.
Data types of some other variables are also changed to be consistent with the
data types returned by matlab functions.
In get_decfun_coef and get_decfun_bias, a zero value is returned in all invalid
cases. We decide not to return NaN because we are not sure if it can be
properly assigned in all platforms. (For example, ``double nan = 0.0/0.0;''
won't compile in Visual Studio.)
add three functions:
get_decfun_coef, get_decfun_bias, and check_regression_model
to linear.def
