DOC - typos

[leahmendelson]

I'm going to consolidate a few typos in the user manual into this issue, focusing on those that could confuse a user:

• Section 2.1 of the user manual (Preparation of an experiment folder) step 3 refers to workfolw.py instead of workflow.py I don't think a user would misunderstand, but given it's the core script for running the code it's worth fixing
• Reference 1 of the user manual has an incomplete journal title

@leahmendelson Thanks, I fixed these typos. I'll leave this issue open in case any other typos are found in the future.

some typos in user manual:

1. Table 4 - method - description: "ihe" should be "the";
2. Table 8 - min_traj_length - description: "has to be larger than min_traj_length" should be "has to be larger than polyorder", I suppose;
3. Table 9 - title: "for the smoothing step" should be "for the stitching step"
