Write a Python script that reads in two unaligned sequences in FASTA
format from a file called "dna_fasta.txt" and outputs the local alignment
scoring matrix V. Submit a hardcopy on Mar 8th in class.

Recall the code for computing V for local alignment is

Input: seq1 (along columns), seq2 (along rows)

Initilization: V[0,0]=0, V[i,0]=ig, V[0,j]=jg

Recurrence:

for i = 1 to length of seq2:
	for j = 1 to length of seq1:
		V[i,j] = max{V[i-1,j-1]+m/mm, V[i-1,j]+g, V[i,j-1]+g, 0}

-------------------------

Complete the local and global alignment matrix V for sequences seq1="CT",
seq2="ACTG", m=10, mm=-2, and g=-5.

		A	C	T	G	
	0	-2	-4	-6	-8	
C	-2
T	-4

Write the complete matrix at the bottom of your Python script and also 
the one outputted from your program.
