make seq at src/

According to the above page, I tried to make seq. Then, I received the following error.

$ make seq

This is because the FFTW3 package is not installed.

Installation of FFTW3

see http://qiita.com/7of9/items/0123202cec8b9a903910

After the installation, as shown in https://github.com/adda-team/adda/blob/wiki/InstallingFFTW3.md ,
we need to set following variables:


FFTW3_INC_PATH	`~/include`
FFTW3_LIB_PATH	`~/lib`

I added followings to ~/.bashrc

.bashrc

### FFTW3 for ADDA (Nov. 23, 2016)
export FFTW3_INC_PATH=~/include
export FFTW3_LIB_PATH=~/lib

make seq at src/

I tried make seq at src/ again.

make seq finished without error.

Now, we can find the execution file named adda under src/seq/.
