A golang project to read the blueprint of an apartment and identify the placements of different chair in different tooms

The layout of an apartment may look as follows :

+-----------+------------------------------------+

./start.sh

go build
go test -v
// to run a specific test
go test -run Test_ReadRoom -v

We now need a command line tool that reads in such a file and outputs the following information:

• Number of different chair types for the apartment
• Number of different chair types per room

The different types of chairs are as follows:
W: wooden chair
P: plastic chair
S: sofa chair
C: china chair

The output must look like as follows:

total:
W: 3, P: 2, S: 0, C: 0
living room:
W: 3, P: 0, S: 0, C: 0
office:
W: 0, P: 2, S: 0, C: 0
