Create README.md

fixed a typo in the project report

added note in test.py to generate trained model

added report

added code to evaluate and print confusion matrix for labelled test data

Trained transfer learning model based on VGG16

added code to run in Colab

added transfer learning notebook: using VGG16's convulation layers for feature extraction and then training dense layers to classify chart image based on those extracted features

fixed url for opening in colab

added code to run notebook in Colab to utilize GPU provided in Colab. Also tried dropouts to reduce overfitting of the model.

added notebook which uses a two CNN layer NN to classify chart images

added dataset and csv files containing training and validation image filenames

added 'image_filename' column in train and val csv files
